Enter two or more fractions separated by "commas"
Ex: 2/3, 5/7 or 3/5, 5/9, 7/3
Given fractions are 473/17,946/223
Formula to find GCF of Fractions is
GCF = GCF of Numerators/LCM of Denominators
As per the formula GCF of Fractions let’s split into two parts and find the GCF of Numerators and LCM of Denominators
In the given fractions GCF of Numerators means GCF of 473,946
Greatest Common Factor of Numerators i.e. GCF of 473,946 is 473 .
LCM of Denominators means LCM of 17,223 as per the given fractions.
LCM of 17,223 is 3791 as it is the smallest common factor for both these numbers.
Lets's calculate GCF of 473,946
11 | 473, 946 |
43 | 43, 86 |
1, 2 |
∴ So the GCF of the given numbers is 11 x 43 = 473
Factors of 473
List of positive integer factors of 473 that divides 473 without a remainder.
1,11,43,473
Factors of 946
List of positive integer factors of 946 that divides 946 without a remainder.
1,2,11,22,43,86,473,946
Greatest Common Factor
We found the factors 473,946 . The biggest common factor number is the GCF number.
So the greatest common factor 473,946 is 473.
Lets's calculate LCM of 17,223
Given numbers has no common factors except 1. So, there LCM is their product i.e 3791
Thus GCF of Fractions = GCF of Numerators/LCM of Denominators = 473/3791
Therefore, the GCF of Fractions 473/17,946/223 is 473/3791
The formula of LCM is LCM(a1,a2,a3....,an) = ( a1 × a2 × a3 × .... × an) / GCF(a1,a2,a3....,an) x common factors(if more than 2 numbers have common factors).
We need to calculate greatest common factor of 17,223 and common factors if more than two numbers have common factor, than apply into the LCM equation.
GCF(17,223) = 1
common factors(in case of two or more numbers have common factors) = 1
GCF(17,223) x common factors =1 x 1 = 1
LCM(17,223) = ( 17 × 223 ) / 1
LCM(17,223) = 3791 / 1
LCM(17,223) = 3791
